Answer:
450 ml.
Step-by-step explanation:
Let x be the amount of water drank by Alla and y be the amount of water drank by Balla.
We have been given that Alla and Balla together drink 750 ML of water. We can represent this information as:
We are also told that Alla drinks 50% more than Balla. We can represent this information as:
From equation (1) we will get,
Upon substituting this value in equation (2) we will get,

Upon distributing 1.5 to right hand side of the equation we will get,

Upon adding 1.5x to both sides of equation we will get,


Let us divide both sides of our equation by 2.5.

Therefore, Alla drank 450 ml of water.
Pay attention cause the factorial will be like this:
<span>4!=4∗3∗2∗1
And the consequent answer will be 24
Hope this works for you</span>
<span>first find the similar term, the similar term is x^2y.
10x^2y + 2xy^2- 4x^2y
group together the similar term and place them in a parenthesis
then perform the operation to simplify the expression.
= </span>(10x^2y<span><span> - 4x^2y
) </span>+ 2xy^2
= ( </span><span>6x^2y ) + </span><span>2xy^2
= </span><span>6x^2y </span><span><span>+ <span>2xy^2 is the sum of the polynomial</span></span> </span>
Answer:
3x-y=6?
Step-by-step explanation:
Answer:
The sum of ages of all 18 pupils in the class = 81
Step-by-step explanation:
Total number of pupil in the class = 18
Average of years in the class = 
Now, 
⇒Average of sum of ages in the class = 4.05
Let us assume the sum of ages of all students in the class = m
By the formula for AVERAGE:


or, m = 18 x 4.5 = 81
Hence, the sum of ages of all 18 pupils in the class = 81
